The use of a venturi and combustion blower fan to mix primary air prior to cumbustion
I have a question on something I’ve run into specifically with Cleveland & Convotherm.
Unlike a grill or a griddle where you turn the knob and it’s either on or off, cleveland uses in their KGL kettles and SGL tilt skillets as well as their Convotherm units what’s called a “Zero gas pressure system” that’s what the first tech support guy I spoke to from Cleveland called it and it stuck with me.
The idea is you draw in the air and the gas using the fan, not relying on the pressure of the gas to give you a preset or correct mix but the fan actually controls it and it can make it hotter or colder depending on how fast it spins.
The C4 model has a feature where it seems like it’ll run slower at times and faster at other times depending on how much heat it has to catch up.
So here’s my question, how can you tell if the flame is proper, you can’t really see it and the only way to adjust it would be to either regulate fan speed or make some larger changes or open the orifice in the gas valve to increase gas flow.
Doing exhaust measurements perhaps?
